ABSTRACT:
A novel inorganic filler-containing polyolefin resin composition exhibits high-level stiffness at a temperature in the vicinity of crystalline melting point of the matrix-forming polyolefin resin or even at a higher temperature. The composition comprises specified amounts of a matrix-forming polyolefin resin, a dispersion-phase-forming resin, and a fibrous or lamellate inorganic filler. In the composition, one end portion of an individual fiber or lamella of the fibrous of lamellate inorganic filler is embedded in the dispersion-phase-forming resin not uniformly miscible dispersed in the polyolefin resin and the other end portion of the individual fiber of lamella is also embedded in the dispersion-phase-forming resin located at a separate position, whereby the filler forms substantially a network structure via the dispersion-phase-forming resin.
